    Sep 01 2019 The separation of pyrite and pyrophyllite by froth flotation is difficult because pyrophyllite the three sheet phyllosilicate is naturally hydrophobic easy-sliming and easily transports to flotation concentrates thus reducing pyrite concentrate grade 2 . Therefore it is almost impossible to separate pyrite and pyrophyllite without any depressant.

    This froth flotation method is used to treat quartz sulfide ores or gold-silver-bearing pyrite and pyrrhotite containing gold telluride pyrrhotite chalcopyrite and other sulfide minerals. The floatable gold telluride in the ores is first produced as a concentrate and then roasted and cyanided to expose gold and silver ores in sulfides and tellurides.
